Beyonce shared a hand-written note in support of marriage equality.

It's the Human Rights Campaign's logo, which is usually a yellow "equals" sign on a blue background. But it has been changed to a pink sign on a red background to support gay marriage.

And celebs are jumping on board.

Beyoncé shared a hand-written note on her Facebook page with her famous song lyrics: If you like it you should be able to put a ring on it.," adding, "We will unite 4 marriage equality."

Ben Affleck didn't go for the red, but posted a photo of President Obama with the quote: "Same-sex couples should be able to get married."

Among those who have changed their profile pics or are using the red logo on Facebook: George Takei (whose change has garnered more than 60,000 likes), Kate Walsh, Felicity Huffman, Jessica Seinfeld and Lance Bass.
